Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an anti-detachment fastening device for automotive aluminum wheel caps. Background Technology

[0002] In the fields of automobile manufacturing, after-sales maintenance, and transportation, aluminum wheel caps are key components that protect wheel hub bearings, prevent dust and water damage, and enhance the aesthetics of the vehicle. Their installation stability directly affects driving safety and the overall quality of the vehicle.

[0003] The device consists of a multi-point elastic claw assembly, an anti-loosening positioning mechanism, an adaptive connecting base, and a convenient installation unit. The device base is fixed to the preset installation position on the wheel hub. After aligning the aluminum wheel cover with the base and pressing it, the elastic claws are squeezed open and automatically fit against the inner wall of the cover. The wedge-shaped locking block is embedded in the slot to complete the initial fixation. The anti-slip rubber pad increases friction, and the double anti-loosening ensures that it will not fall off during driving. When disassembling, the unlocking piece is pried open with a special tool, and the claws retract to remove the cover.

[0004] However, the above-mentioned devices have certain shortcomings in use. Traditional devices rely solely on bolts or clips for fixation, without continuous torque compensation. Vibrations during vehicle operation can cause the bolts to loosen, which can easily lead to safety accidents when the vehicle is traveling at high speed. In view of this, we propose an anti-detachment fastening device for automotive aluminum wheel caps. Utility Model Content

[0020] In one embodiment of this utility model, a reinforcing component 4 is provided on the aluminum hub 1. The reinforcing component 4 includes an arc-shaped cover 41, which is attached to the surface of the aluminum hub 1. An annular plate 42 is fixedly installed on the arc-shaped cover 41. The arc-shaped cover 41 is snapped onto the aluminum hub 1 by fasteners 43. A fastening groove 44 is provided on the aluminum hub 1. An annular plate 45 is fixedly installed on the aluminum hub 1. A round rod 46 is fixedly installed on the annular plate 45. One end of a spring 47 is fixedly installed on the round rod 46. A square rod 48 is fixedly installed on the other end of the spring 47. An installation groove 49 is provided on the aluminum hub 1. A tension spring 410 is fixedly installed between the annular plate 45 and the annular plate 42. Fasteners 43, fastening groove 44, round rod 46, spring 47, square rod 48, and installation... Multiple sets of grooves 49 and tension springs 410 are provided. Fasteners 43 include nut heads 431, anti-slip pads 432 are fixedly installed on nut heads 431, threaded rods 433 are fixedly installed on nut heads 431, and square grooves 434 are opened on threaded rods 433. Fastening grooves 44 include anti-slip grooves 441, which are opened on arc-shaped covers 41. Threaded grooves 442 are opened on aluminum hubs 1. The anti-slip grooves 441 and threaded grooves 442 are positioned correspondingly. Threaded rods 433 are threadedly installed inside threaded grooves 442. Anti-slip pads 432 are set inside anti-slip grooves 441. Tension springs 410 are set inside mounting grooves 49. Square rods 48 slide inside square grooves 434 on threaded rods 433. The fastening direction of threaded rods 433 is consistent with the force direction of spring 47.

[0021] In this embodiment, during installation, the arc-shaped cover 41 is fitted against the surface of the aluminum wheel hub 1, and the threaded rod 433 of the fastener 43 is aligned with the threaded groove 442 of the aluminum wheel hub 1.
